To all fwwm il may concern:

Be it known that I, WALTER L. MARR, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvementsl in Explosive-Engines, of which the following is 4 larities and differences in action in the differentcylinders are compensated for and a valve gearing-is obtained that -is positive and noiseless in operation.

The inventionV consists in the matters'here-v inafter set forth and `more particularly pointed out in the a pended claims.'

In the drawings, igure 1 is a view,v parttially in elevation and partially broken away and in section, of a portion of a motor that embodies features of the invention; Fig. 2 is a view, partially in plan and partially broken away and in horizontal section, of themotor; Fig. 3 is a view in vertical section through one of the cylinders of the motor showing the position assumed at the end of the expansion stroke of the motor; Fig. 4 is a view in elevation of a 40 slight modification of the valve;

valve and floating cylinderheads thereon; Fig. 5 is a sectional view in detailof a and Figs. 6 and 7 are views in detail of the valve.

Referring to the drawings a motor that has a conventional or standard base 1 and crank case 2 is provided with upright cylinders3, arranged en bloc or as desired. A substantially cylindrical rotatable valve 4 that is common to` all the cylinders is journaled horizontally in the upper portion thereof, suitable bearing being afforded. by on the end cylinders and by intermediate bosses 7 formed on the adjacent sides of the intermediate cylinders.

A floating head 9 is disposed in each cylinder to close the -upper end thereof and is journaled on and supportedhyiigglve.

.A suitable packing member 1.0 on the lower end of the floating head prevents leakage :around the cylinder wall. As indicated .in

Fig. 5 the cylinder pressure may be utilized 60.

means of aper- 'to expand' the member 10 by -tiires indicated at 11 that admit the cylinder gases behind the ring. Each head has an Jinlet port 12 .and an exhaust port 13 that register respectively with the intake open- 65 ing 14 and the outlet opening 15.0f the coinpanion-cylinder wall.

.By-passes or channels 16 are formed in the valve 4 each to be turned into register by the rotation ofthe valve with the inlet ,7o

port or exhaust port 13 and connect them successively lwith a' main port 17 in the floating head opening directly-into the cyl# :inder proper. The angular relation of the several by-p-asses or channels -v is suchthat the intake and exhaust of the cylinders occurs in the usual firing relation, the valve ofcourse being operated in timed relation to the engine crank shaft by suitable. connections therefor indicated at "18, so

such connections beingof any preferred type that insure positive interaction between the parts. Preferably the valve is hollow and is water cooled by connection through ahollow stem 19 vand suitable with a pipe 21 leading to the water circula-4 tion system of the cylinders. Or both ends of the valve may have such construction provided the conditions warrant it.- Lubricant is introduced to the valve through suitable oil pipes 22 that communicate with spirally disposed grooves 23 on the valve face. While the .floating head is sulicient to lclose each cylinder -a cap 24 may be secured thereover and included in the water, jacket circulation if desired. There is suilicient play allowed between the upper end face of each floating headvand the cap to permit movement of the former if necessary. Ignition is supplied by the terminal 25 Iinserted at lin the-cylinder wall.

I f desired, the valve may be relieved in vpart of the weight of the floating head and an upward bearing of the latter against the 105 valve insured lby means of a suitably disposed vtween the cap andthe check nut 27, on a stem 28 that passes through guide openings in the cylinder cap into or otherwise attachedto the head suit- @able provision in the of the valves 75 packing gland 20 85 usual spark plug or any convenient spot spring 26 that is 1n compression beand is screwthreaded' 110 designof the adjacent yhiess ont the een 1 "l heed being nee-de against the v .Joint between the neoess ,f ment of :rods and cre In operation the tim-edfnovern valve permits .i charge to eeeh. oylinoer et therprom. ment, cuts on" theI ports' during pression end e. l .osion strokes one?. escape of the usted gases 1 scavenging strokeO @using the end explosion stsolfea es the floot h exposes e. :ieee aree theo. does the valve to der, the
